DETAILED DESCRIPTION
FIGS. 1A ̃1D are perspective views illustrating a transformation process of an electronic apparatus according to an embodiment of the disclosure. Referring to FIG. 1A, in this embodiment, an electronic apparatus 100 includes a first body 110, a second body 120, a supporting frame 130, and a pivoting-locking module 140. The first body 110 may be a tablet computer, and the second body 120 may be an extended keyboard. The second body 120 and the first body 110 overlap with each other. The supporting frame 130 is pivoted to the second body 120. The pivoting-locking module 140 is disposed between the first body 110 and the supporting frame 130.
The pivoting-locking module 140 includes a first pivoting-locking part 142 and a plurality of second pivoting-locking parts 144. In this embodiment, two of the second pivoting-locking parts 144 that are opposite to each other are illustrated as an example. It is noted that, in FIGS. 1A ̃1C, the pivoting-locking module 140 is indicated by dotted lines to clearly illustrate a position of the pivoting-locking module 140. In FIG. 1D, the first body 110 and the first pivoting-locking part 142 are also depicted by dotted lines.
The first pivoting-locking part 142 is fixed to the first body 110. The second pivoting-locking parts 144 are movably attached to the supporting frame 130. The second pivoting-locking parts 144 and the first pivoting-locking part 142 may be locked to each other. When the second pivoting-locking parts 144 and the first pivoting-locking part 142 are locked to each other, the second pivoting-locking parts 144 are pivotable around a first pivot axis A1 relative to the first pivoting-locking part 142, as shown in FIG. 1B.
In addition, the supporting frame 130 is pivotable around a second pivot axis A2 relative to the second body 120, as shown in FIG. 1C, only when the first body 110 is pivoted to a predetermined position relative to the supporting frame 130 by means of the first pivoting-locking part 142 and the second pivoting-locking parts 144. In other words, when the first body 110 is pivoted to a position other than the predetermined position relative to the supporting frame 130 by means of the first pivoting-locking part 142 and the second pivoting-locking parts 144, the supporting frame 130 is pivotable around the second pivot axis A2 relative to the second body 120.
In this embodiment, the first pivot axis A1 is parallel to an overlap direction of the first body 110 and the second body 120. That is, the first pivot axis A1 is parallel to a normal direction N of a display region 112 of the first body 110. Moreover, the second pivot axis A2 is perpendicular to the overlap direction of the first body 110 and the second body 120. That is, the second pivot axis A2 is perpendicular to the normal direction N of the display region 112 of the first body 110.
In this embodiment, the second body 120 includes a keyboard region 122. When the second pivoting-locking parts 144 are pivoted around the first pivot axis A1 relative to the first pivoting-locking part 142, and the first body 110 is pivoted relative to the supporting frame 130 by the locking of the first pivoting-locking part 142 and the second pivoting-locking parts 144, the first body 110 gradually exposes the keyboard region 122, as shown in FIG. 1B.
After the first body 110 completely exposes the keyboard region 122, the first body 110 is in the predetermined position relative to the supporting frame 130, as shown in FIG. 1C, and the supporting frame 130 is pivotable around the second pivot axis A2 relative to the second body 120, so that the first body 110 may be lifted relative to the second body 120.
Therefore, when text input is required, the user only needs to pivot the first body 110 to the predetermined position relative to the second body 120, i.e. the first body 110 is in a position that completely exposes the keyboard region 122, and then pivot the supporting frame 130 relative to the second body 120 to lift the first body 110 that is locked to the supporting frame 130. The electronic apparatus 100 allows the user to input text via the keyboard region 122 of the second body 120 while watching the display region 112 of the first body 110, which is similar to the use of a laptop.
In this embodiment, the second body 120 further includes a receptacle space 120a for accommodating the supporting frame 130 and the pivoting-locking module 140. When the first body 110 and the second body 120 overlap with each other, the supporting frame 130 and the pivoting-locking module 140 are accommodated in the receptacle space 120a, which reduces the thickness of the electronic apparatus 100 and miniaturizes the electronic apparatus 100.
FIG. 2A is an exploded view of the pivoting-locking module and an ejector of FIG. 1D. FIG. 2B is an exploded view of the pivoting-locking module and the ejector of FIG. 2A from another aspect. FIG. 3 illustrates a rotation of an ejecting shaft of FIG. 2A. With reference to FIGS. 2A, 2B, and 3, the electronic apparatus 100 further includes an ejector 150, which is disposed between the second body 120 and the supporting frame 130. The ejector 150 pushes the supporting frame 130 relative to the second body 120, so that the supporting frame 130 is pivoted around the second pivot axis A2 relative to the second body 120 (shown in FIG. 1D). In addition, the ejector 150 is used to push the first body 110 to a predetermined angle relative to the second body 120 (as shown in FIG. 1D). Therefore, the first body 110 is not blocked by the second body 120 and does not hinder the user from operating the first body 110 or the second body 120.
More specifically, the ejector 150 includes an ejecting shaft 152 and an elastic element 154, wherein the elastic element 154 may be a torsion spring. The ejecting shaft 152 is pivoted to the second body 120. The elastic element 154 is disposed between the second body 120 and the ejecting shaft 152 and pivots the ejecting shaft 152 relative to the second body 120.
When the first body 110 and the second body 120 overlap with each other, as shown in FIG. 1A, the supporting frame 130 and the pivoting-locking module 140 are accommodated in the receptacle space 120a (as shown in FIG. 1D), and the ejecting shaft 152 (as depicted in dotted lines in FIG. 3) is pressed by the supporting frame 130 and received in the receptacle space 120a. 
On the other hand, when the first body 110 completely exposes the keyboard region 122, as shown in FIG. 1C, the ejecting shaft 152 is not pressed by the supporting frame 130, and thus the ejecting shaft 152 (as depicted in solid lines in FIG. 3) is raised by an elastic force provided by the elastic element 154 and supports the supporting frame 130 to maintain the first body 110 in a lifted position, as shown in FIG. 1D.
With this configuration, when the first body 110 is in the predetermined position of FIG. 1D relative to the second body 120, the supporting frame 130 is ejected by the elastic element 154 of the ejector 150, so as to automatically lift the first body 110 and strengthen the support of the supporting frame 130.
Referring to FIGS. 2A and 2B, the pivoting-locking module 140 of this embodiment further includes a recovering element 146 disposed between the second pivoting-locking parts 144. In addition, each of the second pivoting-locking parts 144 includes a protrusion 144a, and the supporting frame 130 includes a plurality of holes 130a respectively corresponding to the positions of the protrusions 144a. The protrusions 144a respectively pass through the corresponding holes 130a to be fixed to the recovering element 146, so as to enable the recovering element 146 to move the second pivoting-locking parts 144 relative to the supporting frame 130.
Therefore, when the second pivoting-locking parts 144 are opened/closed relative to the supporting frame 130, the recovering element 146 is able to recover the locking between the second pivoting-locking parts 144 and the first pivoting-locking part 142. In this embodiment, the recovering element 146 is, for example, an elastic body, such as a flat spring module.
In this embodiment, the pivoting-locking module 140 further includes a plurality of latches 148, which are respectively fixed to the second pivoting-locking parts 144. When the latches 148 respectively receive an external force, the latches 148 are moved relative to the supporting frame 130, which concurrently moves the corresponding second pivoting-locking parts 144. With this configuration, the relative movement between the latches 148 is used to release the locking between the first pivoting-locking part 142 and the second pivoting-locking parts 144, so as to separate the first body 110 from the second body 120. Moreover, after the latches 148 are moved relatively, the second pivoting-locking parts 144 are moved back to the original positions by the elastic force provided by the recovering element 146, so as to lock the first pivoting-locking part 142 to the second pivoting-locking parts 144 again.
Furthermore, each of the second pivoting-locking parts 144 respectively includes a plurality of sliding blocks 144b, and the supporting frame 130 includes a plurality of sliding grooves 130b respectively corresponding to the positions of the sliding blocks 144b. When the sliding blocks 144b pass through the supporting frame 130 to be fixed to the corresponding latches 148, the sliding blocks 144b are maintained slidable in the sliding grooves 130b, so as to slidably attach the second pivoting-locking parts 144 to the supporting frame 130. With this configuration, the positions of the second pivoting-locking parts 144 are adjustable so as to be locked to the first pivoting-locking part 142.
FIG. 4 is a schematic cross-sectional view showing the locking between the first pivoting-locking part and the second pivoting-locking part of FIG. 2A. Referring to FIGS. 2A, 2B, and 4, the first pivoting-locking part 142 of this embodiment includes a circular groove 142a, and each of the second pivoting-locking parts 144 includes an arc flange 144c. When the arc flanges 144c are locked to the circular groove 142a, the first body 110 is integrated with the second body 120 (as depicted in FIG. 1D), and the arc flanges 144c are maintained pivotable in the circular groove 142a, so as to pivot the first pivoting-locking part 142 and the second pivoting-locking parts 144 around the first pivot axis A1 (as shown in FIG. 1D).
It is noted that, in this embodiment, the two second pivoting-locking parts 144 are symmetrically disposed on the supporting frame 130 and thus FIG. 4 illustrates one arc flange 144c fitted to the circular groove 142a as an example.
Moreover, the first pivoting-locking part 142 includes a first guiding slant surface 142b, and each of the second pivoting-locking parts 144 includes a second guiding slant surface 144d. Therefore, when an external force is applied to lock the second pivoting-locking parts 144 and the first pivoting-locking part 142, the first guiding slant surface 142b and the second guiding slant surfaces 144d are coordinated with each other to guide and lock the first pivoting-locking part 142 and the second pivoting-locking parts 144. Accordingly, the first body 110 is integrated with the second body 120.
To conclude the above, the first body and the second body of the disclosure are locked and pivoted by the pivoting-locking module, and the integrated two bodies of the electronic apparatus form various appearances to satisfy different requirements in different occasions. In addition, when the electronic apparatus includes the ejector, the supporting frame is ejected by the elastic force of the elastic element for automatically lifting the first body and strengthening the support to the supporting frame. Furthermore, the second body has the receptacle space. When the first body and the second body overlap with each other, the supporting frame and the pivoting-locking module are accommodated in the receptacle space, which facilitates the miniaturization of the electronic apparatus. Moreover, the pivoting-locking module further includes the recovering element or the plurality of latches for facilitating the disassembly of the first body and the second body.
It will be apparent to those skilled in the art that various modifications and variations may be made to the structure of the disclosure without departing from the scope or spirit of the disclosure. In view of the foregoing, it is intended that the disclosure cover modifications and variations of this disclosure provided they fall within the scope of the following claims and their equivalents.
